Problems solved by technology

Its disadvantages are: there is no wire rope pressing and retracting device. When the electric crane lifting mechanism is used to hoist the goods, it is easy to cause the wire rope to be wound around the drum, and the wire rope will be loose and loose.
Unable to satisfy multi-frequency lifting and hoisting of goods

Abstract

The invention belongs to design techniques of electric cranes, and further relates to the improvement on the lifting mechanism of an aviation airborne electric crane. The lifting mechanism is characterized in that a steel wire rope pressing mechanism is arranged outside a rectangular window; and the steel wire rope pressing mechanism comprises two torsional springs (6), a driven gear (7b), a torsional spring shaft (8), a right torsional spring shaft seat (9), a right pressing barrel (10), two swinging arms (16), a left pressing barrel (17), a liner bushing (18), a locating pin (19), a flat key(20) and a left torsional spring shaft seat (21). According to the lifting mechanism of the aviation airborne electric crane provided by the invention, when goods are lifted by the lifting mechanismof the electric crane, that the steel wire rope is quickly wound on the winding drum smoothly and orderly is ensured, the electric crane realizes the high-frequency goods lifting function, and practical working requirements are met.

Description

technical field [0001] The invention belongs to the design technology of electric cranes, and relates to the improvement of the lifting mechanism of electric cranes carried by aviation. Background technique [0002] The aviation electric crane is used for hoisting goods in the cargo compartment of the transport aircraft. The structure of a current electric crane lifting mechanism can be found in figure 1 , comprising a drive motor assembly 1, a reel assembly 3, a crane lifting mechanism housing and a wire rope 14; the crane lifting mechanism housing includes a left end cover 4a, a cylinder 4b and a right end cover 4c, and the left end cover 4a is fixed to the cylinder 4b by screws On the left port of the cylinder body 4b, the right end cover 4c is fixed on the right port of the cylinder body 4b, and a rectangular window for storing the wire rope 14 is opened on the cylinder body 4b; the drum assembly 3 includes a drum shaft, a left drum and a right drum, The left drum and ...
